Enhancing security in Banking Application for low cost RFID tag

RFID (Radio Frequency identification) is a wireless identification technology used to identify and track objects using radio frequency waves. It has pierced into all the sectors like supply chain automation, asset tracking, manufacturing and supply chain management, retailing, Warehousing, agriculture, traffic, transportation and banking due to its increased functionality and easy- to-use capabilities. It has its own attractiveness because of no line of sight is required between the reader and the Antenna. The role of RFID in banking is of more importance to improve customer satisfaction, avoid counterfeiting, financial document management, electronic payments using contactless cards and access control to resources. RFID tag cloning is one of the common attacks found in the RFID system. Our work uses low-cost tags where cloning of tags could lead to big damage. To improve access security and privacy in banking sector this paper introduces the new authentication protocol which prevents the tag from cloning. EPC Class1 Gen2 standard is considered as a universal specification for low cost RFID tags, but assurance is not given for the security. A new lightweight authentication protocol based on Gen2 is proposed to resist the attacks tracing and cloning using the method of CRC, PRNG and BAN logic. The result shows that the enhanced protocol of GEN2 meets the Enhancing Security Standard.
